PICTUREQWJFKCZII met-ear.

To aLZ whom it may concern Be it known that we. Ravaro: and EDWARDGatit'irrnax, cl United States, residing at- Mum have invented certainnew and useful lnr provements in Picture-iiiachine Mipliances, of whichthe following is a specification.

This invention relates to improvements in picture machine appliances,and has "for its object to provide a device to be used in connecticnwith a moving picture machine whereby the work of handling the film maybe facilitated and the wear and tear on the film in its beingpassed'from and to its reel,

be minimized.

4n the operating of the moving picture machine, the film is passed fromthe reel and across the face of the machine lens, and is carriedthenceonto a suitable receiving reel. The machine is equipped with yieldableguide or retaining bars at the sides of the path of the film that areengaged by the edges of the film and serve to maintain the latter intrue alinement as it passes the face of" the lens. Other engagingsurfaces are so arranged that while there is free travel of the film,yet it is retained against transverse displacement and at the sametimeis prevented from puckering or warping. In the practice of operatingthese film machines it is found. that in the passing over these holdingor retaining surfaces, of the film, there occurs a gritty depcsit orprecipitation at the faces the metal guides. This gritty or carbonlikedepcsit adheres to the metallic *faces of the said guides with suchtenacity that cutting or ahrasirn of the film. occurs, and accordinglythe edges of the film become mutilated and weakened, and with theconsequent i ipairment of the film, fracture and tearing of same finallyresults. The necessitv of winding and re-winding these films beingfrequent, the abrasion and injury to same as above indicated, unlessprevented, comparatively soon renders the edges f the film very weak andfragile, and renders the operation of same so uncertain thatinterrupticn in its travel occurs.

The objects of this invention are tojprw Specification of LettersPatent.

if-ii a os in the machine. is ininimi' zed. and the tenden y ofprccipitatirn (:r adhesirn at surfaces of foreign particles, is overcome. These chjccts. and ther purposes which will be apparent as thenature of our inventiin hotter uuderstocd, are accompl l ed by and theinveutir'n is embodied in the new ccnstructirn. ccmhinatirn and anrangement of parts illustrated in the accompanying drawings. descrihedin this specification. and defined in the appended claims.

Similar characters of reference are applied tothe several parts of theinvention as the same appear in the different views in the drawings, inwhich Figure l is a side view of the invention. Fig. 2 is a top planview of Fig. 1. Fig. 3 is an end view, taken in tne direction indiczttedby the arrow 8 in Fig. l. Fig. 4 is a view showing the invention inposition in readiness for rperatirn. Fig.5 is a detailed view of pne ofthe clutch rings.

' v The frame consists of side plates A and A that rise from a bottomplate 1U. These side plates are provided with pairs of bosses 3 and Cpositioned relatively to each other as shown, and which constitutehousings in which are disposed the pairs of luhricator studs l) and E.The studs are cylindrical and are of a non-friction compositicncontaining lubricant of proper nature capable of being taken up by theperforated edge of the filmmoving in contact with same. These stubs, aredirectly retained in clutch rings F disposed in the bores of the saidbosses. Each of these clutch rings consists of a re silient cylindricalshell divided longitudinally as shown in Fig. 5. On the external face ofthis clutch ring is a tocth F which fits into a recess therefor (notshown) in the bore of thehcssf To tighten this clutch ring against itsstub and thereby to hold the latter'securely at adjusted position, theset screw G is screwed down on the clutch ring.

that frirllrn at the hearing or guiding sur roller has flanges I-Ispaced apart a suitable distance to constitute bearings over which theedges of the film may travel. The pin K which constitutes a journal forthe guide roller, rests in holes provided therefor in the wall plates Aand A The rear end. of the said pin K is provided with a head K. Theforward end of the pin has an elbow joint I sufficiently stiff that thearm K turned to its position as shown in Fig. 2, retains the pin againstdisplacement. When it is necessary or desired to remove this pin, thearm K is turned to straight or longitudinal position,-the pin may bethen simply slipped free from its bearings, and the guide roller H isreleased. The frame just described is supported on a base plate L'of thegeneral form and proportion shown; the bottom plate A has its endsloosely retained by guide bars L, and the said frame is capa-.

ble of being shifted on said base nlate.

At Fig. 4 is shown the usual arrangement of the reels as placed on theoperators bench.

' These reels are supported on suitable standards 3 and 4 at the usualdistance apart. In the said bench, at proper location between the reelsis provided an opening which is bridged by a panel of glass. A lamp (notshown) positioned underneath this glass affords light'from below so thatthe operator may ha e the proper view of the film when examination orrepair of thereof may .be necessary. In the base plate L we provide anopening M of proper dimensions to register with the said glass.

The mode of practising our invention may be readily understood. Thedevice in readiness for'use appears as shown in Fig. 2. The base plateis secured by screws 5 to the operators bench, with its opening atregistraticn with the glass bridge. The frame is slipped from theshifted or translated location shown, to location in alinement with thereels; in this instance-the dotted line position. The end of the film isthen passed underneath guide-roller H thence above the stubs E, thencebelow stubs D, and then to reel 1. By the usual rotation then, of reel 1in the business of winding the film, the operation of the invention issuch that as the said reel is actuated, the film, its edges bearinglightly on the polished flanges of the guide roller II, passes slidinglyin hearing contact withthe ends of the stubs E, and in similar bearingcontact with the ends of the stubs D, both sides of each'edge of thefilm being treated to the lubricant carried by the stub ends. The edgesof the film being perforated there is a gathering or picking up by theedges of these perforations of a sufficient quantity of the lubricant toafford lubrication for the edges of the said perforations their jpassingover the sprocket teeth of the wheels in the machine. At the same timethere is a lubrication of the body portion of the film at these edges sothat in the passing of same over the holding or guide members heretoforedescribed as part of the machine, there is a minimum.

2, which leaves free the space above the.

glass panel where the work or examination and repairing is done. Intheir proper position the stubs are set so that the extent of sameinwardly is sufficient to afford contact of the edges only, of the film.By virtue ofv this arrangement and of that of the guide roller, the faceportion of the film has no contact with any part of the machine, at thesame time there is such correct guiding of the film that the windingthereof from one reel to the other, at high speed,is not interferedwith. tlhe efiiciency of this invention is especially apparent in thecase of first run or brand new films. The passing of a new film throughthe picture machine, the first time, besides being noisy, is accompaniedby such a clogging and fouling at the guide bars, and the friction is sohighly abnormal, that abrasion and v. eakeningof the edges of tlie filminvariably follows. Actual mutilation and fracture of the film may beprevented only by stopping the'operation of the machine and scraping andcleaning the guide members. In some instances, the fouling of theseguide or keeping members has been so severe that same have had to beentirely removed and repolished.

In thepractice of our invention the stubs E and D do not need to bere-set or placedafter they have been once adjusted to the properpcsitionto properly accommodate the edges of the film. The effect on theends of the stubs, by the'repeated passing thereof of the film, isgradually to wear away or sever the end of the stub. When this hasoccurred, the stubs are simply again moved having -eheir ends projectedinwardly, and a roller element arranged between the supperts and everwhich the film is passed in its iravel' Over one pair of stubs and underthe ether pair of stubs.

2. A film lubricating device comprising a frame having supports, pairsof stubs carried by said supports and which have their ends projectedinwardly, a roller arrange 1 10 between the supports over which topass/she film in its travel over one pair of stubs and under the otherpair (if-stubs.
